The whole fish tank thing gets to me too. One time I saw a late 40s Philco 10" b/w console at a thrift in excellent condition, and decided to just come back the next week for it, because I didn't really have time to deal with it then. When I came back the next week, I learned that it was sold to a guy who wanted to fish-tank it. Since then, I've felt like I had to rescue every old TV I saw even if it isn't one I really wanted, in case someone otherwise turns it into a fish tank. And now I have 40 sets in a 1 bedroom apartment. There's got to be a solution to this, but I have yet to find it.
